💖 NAME 💖

afs_ptserver_selinux — Security Enhanced Linux Policy for the afs_ptserver processes. Bestie, this is page afs_ptserver_selinux(8), and the manual name is SELinux Policy afs_ptserver — yes, it’s a whole vibe, and it’s all about the afs_ptserver processes. 🎀

---

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the afs_ptserver processes via flexible mandatory access control. Slay for mandatory access control, honestly. 💅

The afs_ptserver processes execute with the afs_ptserver_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep afs_ptserver_t

---

🦋 ENTRYPOINTS 🦋

The afs_ptserver_t SELinux type can be entered via the afs_ptserver_exec_t file type.

The default entrypoint paths for the afs_ptserver_t domain are the following:

• /usr/afs/bin/ptserver
• /usr/libexec/openafs/ptserver

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system.

You can see the context of a process using the -Z option to ps.

Policy governs the access confined processes have to files. SELinux afs_ptserver policy is very flexible allowing users to setup their afs_ptserver processes in as secure a method as possible. Iconic behavior, no cap. 🌟

The following process types are defined for afs_ptserver:

• afs_ptserver_t

Note: semanage permissive -a afs_ptserver_t can be used to make the process type afs_ptserver_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

---

💜 BOOLEANS 💜

SELinux policy is customizable based on least access required. afs_ptserver policy is extremely flexible and has several booleans that allow you to manipulate the policy and run afs_ptserver with the tightest access possible. Tightest access possible = the moment. 🔥

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

---

🌸 MANAGED FILES 🌸

The SELinux process type afs_ptserver_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

• afs_logfile_t — default path: /usr/afs/logs(/.*)?
• afs_pt_db_t — default path: /usr/afs/db/pr.*

---

🎀 FILE CONTEXTS 🎀

SELinux requires files to have an extended attribute to define the file type.

You can see the context of a file using the -Z option to ls.

Policy governs the access confined processes have to these files. SELinux afs_ptserver policy is very flexible allowing users to setup their afs_ptserver processes in as secure a method as possible.

🌈 STANDARD FILE CONTEXT 🌈

SELinux defines the file context types for the afs_ptserver. If you wanted to store files with these types in different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t afs_ptserver_exec_t '/srv/afs_ptserver/content(/.*)?'
restorecon -R -v /srv/myafs_ptserver_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for afs_ptserver:

• afs_ptserver_exec_t — Set files with the afs_ptserver_exec_t type, if you want to transition an executable to the afs_ptserver_t domain.
  • Paths: /usr/afs/bin/ptserver, /usr/libexec/openafs/ptserver

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.

---

💅 COMMANDS 💅

semanage fcontext can also be used to manipulate default file context mappings.

semanage permissive can also be used to manipulate whether or not a process type is permissive.

semanage module can also be used to enable/disable/install/remove policy modules.

semanage boolean can also be used to manipulate the booleans.

system-config-selinux is a GUI tool available to customize SELinux policy settings.
